I'm running a squeezebox touch connected to a Sony receiver using an analogue cable. Both the Touch and receiver have digital and optical connections. Will I notice the difference in sound if I change from analogue cable to digital/optical cable? As a reference I've been listening to the only flac files I have (Beatles remastered set) and to my amateur ear it sounds pretty good with analogue connection. Also I'm not a huge audiophile .......I never realised that one of my speakers was out of phase until I ran the automated setup in the receiver! Any advice greatly appreciated.

All of the SBT outlets are live simultaneously so it's easy to test and see which sounds better.
It largely depends on the quality of the receiver. The SBTs DAC is pretty good in its own right.

Just try, many reciveirs has no analog path so analog signals are digitised again so the Touch good dac is of limited use .

Be aware that the level can differ between inputs try to make them even before serius comparision.

That's a good point. My Receiver (Onkyo) does have an analogue path and also a "direct" digital mode ie where it processes the digital signal as is without any additional "listening mode" processing.

it gets very rare to have that analog passthru these days and for good reasons .( It was an exclusive option for a while and an asked for feuture during the transistion from analog to digital ) .

You dont even get the subwoofer xover without going the digital path in the reciever. analog passthru is usually strictly 2ch .

Or aditional listenings modes in my meridian system there are some that actually works for music (not gimmics ) .

The analog sources are "legacy sources" even the crumiest of todays ADC chips has no problem exceeding the performance of those.

Doing a simple thing like volume controll can actually be cheaper and better in the digital domain (even budget recievers operates in floating piont and 24 bits ).
So you best reasonably priced preamp migth be the ADC to DAC route anyway , those very expensive very good analog potentiometers probably cost more then all the compenenents in a reciever.
Not to mention that tone controlls and balance would be much better done digitally .

it can actually be hard to hear any difference, if the recievers ADC is good and its DAC is good the added noise thd im and whatnots may never reach humanly perceptible levels especially in a normal home environment at reasonable volume levels .

But in priciple i'm for using the digital inputs on recivers ,thats how you are meant to use them anyway .
They toss in analog ins for grannys old VHS or some old satelite reciever you migth have :) i dont supose anyone has any cassettes left either they dont age well ( I ditched my last cassete deck in the early 90's ) .
But its good for some vinyl nostalgia , if you have an LP player .

What, no tape deck?! I still have one, as you can see in my signature. OK, it's a vintage system from the late 1970ies, but works like a charm.

But to be honest, just yesterday, while at an event of experimental electronic music, I bought 3 tapes by some of the artists there, together with some 7" vinyl :)

I se and a good old Thorens ! i had a Thorens when i was younger .

Yes it's the latest thing to release on cassette again :) it's a bit cute that electronica artist does it .

I had a half decent Alpine not thier best but decent . I've probably had the only calibrated one ever, my dad took it to the technicians at the pulic service radio (SR Sveriges Radio ) where he worked at the time and had them tune it for me with calibrations tapes and whatnot's corect azimuth for the tape head etc. I think my VU meters was actually correct ,they ar just a ligth show on most consumer machines :) Realy what a horrible end user format less than <1% of the users could record corretly on them . What about double speed dual cassete decks for copies thats hifi :) (or not so much ) .

More OT trivia in the end it's life the actual tapes had better performance than most players , not many could use the best metal tapes potential . the heads saturated before the tape in the treble

I've found that quality blanks (TDK and Maxell) have aged just fine but pre-recorded titles are likely to drag and squeal.

I still play reels, too!

Even more obscure, I use analog quadraphonic decoders and am disturbed at the disappearance of multichannel analog inputs on most new equipment.
